0f45b97eda regions now make use of nested top actions, so they're almost correct. (Still need to lock freed regions until end of transaction.) 2006-07-25 00:56:50 +00:00

d26263262b Completely new blob implementation. Slower than the old one was supposed to be, but is correct, and extremeley 
simple.  It simply writes the pre-image and post-image of each blob to the log using TpageSet.

3e4cac0fe3 Continued cleaning up allocation code. It seems really slow all of a sudden, so this commit probably introduced a performance bug. 2006-06-17 00:25:09 +00:00

e56c46b95c Moved blob_record_t into transactional.h (part of transition to using 
slot type lookup tables.)

e0b34633ec Fixed broken min_rec_lsn() semantics; before, if there were not outstanding transactions / writes, 
then these calls would return flushedLSN().  The problem was that flushedLSN wasn't guaranteed to
return a pointed to the beginning of a log entry.

c1d8906d28 removed memcpy() calls from inMemoryLog; added "const" qualifier to many LogEntry pointers. 2006-04-11 02:20:21 +00:00

d3d7f2c788 Implemented "LOG_TO_MEMORY", which mostly works (linear hash NTA goes into an infinite loop....) 2006-04-07 03:40:40 +00:00

1c979f3052 Factored logWriter.h out of the rest of the system. The only file that directly depends on it is logger2.c, which can 
now dispatch requests to different (hardcoded) log implementations.

345f0cde78 Added the base functionality and test case for the BTree... just a hello world method. but it has the h, c and check files. -colleen ;) 2005-05-05 21:34:12 +00:00

ee9eb416ea Implemented fifo pool that allocates entries out of a pool (it should be easy to extend this to avoid deadlock, while allowing it to continue to provide backpressure) 2005-03-23 08:07:53 +00:00

bf4be359b3 Partially refactored logMemory and multiplexer into a fifo implementation. Added support to fifoPool for 
asynchronous threads running round-robin through the dirty fifos consuming entries in idle ones.

80ed16c18e Initial implementation of logMemory.c. Haven't yet done any testing, but it seems to compile. However, as of now, the current source code in the cvs repository does not build, dying on check_<somehting (I think ringbuffer.x)>, due to an a reference to an undefined symbol 'mutex'. 2005-03-14 20:54:06 +00:00

1bfb634103 Preliminary benchmark program uploads for SEDA-style response time percentiles vs requests / second 
Also added a few cute little utilities:
  - truncate_log
  - run_recovery

Upped max # of concurrent transactions.  (Current throughput during benchmarking remains ~flat up to 32,000
threads, but past max concurrent transactions was 1,000...)
